Moulding Ceramic Circuit Board Substrates: Cov txheej txheem feem ntau siv

Hauv tsab ntawv blog no, peb yuav saib ntau txoj hauv kev uas siv los tsim cov khoom siv hluav taws xob ceramic substrates.

Moulding ntawm ceramic circuit board substrates yog txheej txheem tseem ceeb hauv kev tsim khoom siv hluav taws xob. Ceramic substrates muaj thermal stability zoo heev, muaj zog txhua yam thiab tsis tshua muaj thermal expansion, ua rau lawv zoo tagnrho rau kev siv xws li hluav taws xob hluav taws xob, LED thev naus laus zis thiab automotive electronics.

1. Moulding:

Moulding yog ib txoj hauv kev siv ntau tshaj plaws rau kev tsim cov khoom siv hluav taws xob hauv hluav taws xob. Nws koom nrog kev siv hydraulic xovxwm los compression ceramic hmoov rau hauv cov duab predetermined. Cov hmoov yog thawj zaug tov nrog binders thiab lwm yam additives los txhim kho nws ndlwg thiab plasticity. Tom qab ntawd cov sib tov yog poured rau hauv pwm kab noj hniav thiab lub siab yog siv rau compact lub hmoov. Lub resulting compact yog ces sintered ntawm high kub kom tshem tawm cov binder thiab fuse cov ceramic hais ua ke los tsim ib tug khoom substrate.

2. Casting:

Daim kab xev casting yog lwm txoj kev nrov rau ceramic Circuit Board substrate tsim, tshwj xeeb tshaj yog rau nyias thiab hloov tau yooj yim substrates. Nyob rau hauv txoj kev no, slurry ntawm ceramic hmoov thiab hnyav yog kis mus rau ib qho chaw tiaj tus, xws li cov yas zaj duab xis. Tus kws kho mob hniav los yog cov menyuam yog siv los tswj lub thickness ntawm slurry. Cov kuab tshuaj evaporates, tawm hauv nyias daim kab xev ntsuab, uas tuaj yeem txiav mus rau hauv cov duab xav tau. Cov kab xev ntsuab yog ces sintered kom tshem tawm cov kuab tshuaj uas tseem tshuav thiab khi, uas ua rau muaj qhov ntom ntom ntom ntom ntom.

3. Txhaj tshuaj molding:

Kev txhaj tshuaj molding feem ntau yog siv rau molding yas qhov chaw, tab sis nws kuj siv tau rau ceramic Circuit Court board substrates. Cov txheej txheem yuav tsum tau txhaj tshuaj ceramic hmoov sib tov nrog ib tug binder rau hauv pwm kab noj hniav nyob rau hauv siab. Cov pwm yog ces rhuab kom tshem tawm cov binder, thiab lub resulting ntsuab lub cev yog sintered kom tau qhov kawg ceramic substrate. Txhaj tshuaj molding muaj qhov zoo ntawm cov khoom siv ceev ceev, qhov nyuaj geometry thiab qhov tseeb qhov tseeb.

4. Extrusion:

Extrusion molding feem ntau yog siv los tsim cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob nrog cov duab sib luag, xws li cov raj lossis lub tog raj kheej. Cov txheej txheem cuam tshuam nrog kev yuam cov yas ceramic slurry los ntawm pwm nrog cov duab uas xav tau. Cov muab tshuaj txhuam yog txiav mus rau hauv qhov xav tau ntev thiab qhuav kom tshem tawm cov seem uas muaj dej los yog hnyav. Cov qhuav ntsuab qhov chaw raug rho tawm haujlwm kom tau txais qhov kawg ceramic substrate. Extrusion enables qhov nruam zus tau tej cov substrates nrog zoo ib yam qhov ntev.

5. 3D luam ntawv:

Nrog lub advent ntawm additive manufacturing technology, 3D printing yog ib tug siv tau txoj kev rau molding ceramic Circuit Court board substrates. Nyob rau hauv ceramic 3D printing, ceramic hmoov yog tov nrog ib tug binder los ua ib tug printable paste. Tom qab ntawd cov slurry yog muab tso rau hauv ib txheej los ntawm txheej, ua raws li lub computer tsim. Tom qab luam ntawv, cov khoom ntsuab yog sintered kom tshem tawm cov binder thiab fuse cov ceramic hais ua ke los tsim ib qho khoom substrate. 3D luam ntawv muaj kev tsim qauv yooj yim thiab tuaj yeem tsim cov txheej txheem nyuaj thiab kho kom haum.

Hauv luv

Lub molding ntawm ceramic Circuit Board substrates tuaj yeem ua tiav los ntawm ntau txoj hauv kev xws li molding, daim kab xev casting, txhaj tshuaj molding, extrusion thiab 3D luam ntawv. Txhua txoj kev muaj nws qhov zoo, thiab qhov kev xaiv yog raws li qhov xav tau ntawm cov duab, cov khoom siv, qhov nyuaj, thiab tus nqi. Qhov kev xaiv ntawm txoj kev tsim thaum kawg txiav txim siab qhov zoo thiab kev ua tau zoo ntawm cov ceramic substrate, ua rau nws yog ib qho tseem ceeb hauv kev tsim khoom siv hluav taws xob.
